We're dividing 6815580 by 77 
Our goal is to divide 6815580 by 77.

On to step 1:
If we divide 6 by 77, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 77

Advancing to step 2:
77 can be fit into 68 0 times, resulting in a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Bring next digit (1) of the dividend behind the 68 and repeat the process: 681 / 77

Going ahead to step 3:
When dividing 681 by 77, we get 8 with a remainder of 65.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 616 from 681 and we're left with 65.
Bring next digit (5) of the dividend behind the 65 and repeat the process: 655 / 77

Step 4:
655 divided by 77 is 8 with a remainder of 39.
Use 8 as the next digit of our solution. 
Result so far: 88.0
Deduct 616 from 655 and we're left with 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 77

Let's proceed to step 5:
395 divided by 77 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 885.0
Subtract 385 from 395 to get 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 77

Going ahead to step 6:
77 goes into 108 1 times with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 8851.0
Deduct 77 from 108 and we're left with 31.
Include the next digit (0) from the dividend after 31, then repeat: 310 / 77

Advancing to step 7:
77 goes into 310 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 88514.0
The remainder is 2 after subtracting 308 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
When dividing 20 by 77, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 88514.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
77 goes into 200 2 times with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 88514.02
The remainder is 46 after subtracting 154 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 10:
If we divide 460 by 77, we get 5 and a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 88514.025
The remainder is 75 after subtracting 385 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 11:
77 goes into 750 9 times with a remainder of 57.
The next digit of our result is 9. 
Result so far: 88514.0259
Subtract 693 from 750 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 12:
77 goes into 570 7 times with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 88514.02597
If we take 539 away from 570, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
The number 77 fits into 310 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 88514.025974
The remainder is 2 after subtracting 308 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
The number 77 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 88514.025974
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 15:
If we divide 200 by 77, we get 2 and a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 88514.02597402
Subtract 154 from 200 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 88514.02597402 with a remainder of 4.6e-08.
